I'm a newbe to th xbox scene & i downloaded Metal gear solid the DVD vernot knowing how big it really was, so i had to Jam a old 20 gig drive in the xbox, than this prob came up with the NTFS file system, I didn't feel like waiting for the Rip ver of MGS2S

Can someone show me how this is done without reformating the drive & losing all my info, is there another way!

OK, To the orig question on how to convert the drive. If and only if you're running win 2000 or xp, click start, run. then type "cmd" and ok. It'll pop up the command prompt. there type "convert c: /fs:ntfs" that will convert the hd to ntfs file system.
